Question

A car accerlates from 6metre sec1 in 10sec calculate the accerlation and the distance covered by the car in that time
​

Answer 1

Solution :—

Given :-

• Initial Velocity (u) = 6 m/s
• Final Velocity (v) = 0 m/s
• Time Taken (t) = 10 a

To Find :-

• Acceleration (a)
• Distance Travelled (s)

Calculating Acceleration

Formula Used :-

• v = u + at

⟹ 0 = 6 + a × 10

⟹ 0 = 6 + 10a

⟹ -6 = 10a

⟹ 10a = -6

⟹ a = -6/10

⟹ a = -0.6

Thus, acceleration is -0.6 m/s²

Note :- If there is a negative sign it denotes that there is a negative acceleration i.e retardation

Calculating Distance Covered

Formula Used :-

• v² - u² = 2as

⟹ (0)² - (6)² = 2 × -0.6 × s

⟹ 0 - 36 = -1.2 s

⟹ 1.2 s = 36

⟹ s = 30

Thus, Distance Covered is 30 m

Hence, Solved ♡
